Question

For the phosphite (PO3)3- Giving all the steps write the lewis structure​

Answer 1

Explanation:

p should come in the middle and oxygen around the phosphorus as oxygen has doublebond and p has 4 electron gain one oxygen contains double bond and other 2 contains 1 bond

Answer 2

The Lewis-dot structure of $PO_3^{3-}$  is shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.

In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.

The given molecule is, $PO_3^{3-}$

As we know that phosphorous has '5' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in $PO_3^{3-}$  = 5 + 3(6) + 3 = 26

According to Lewis-dot structure, there are 6 number of bonding electrons and 20 number of non-bonding electrons.
